Tired of remembering dozens of passwords? Your body may be the only key you will need in the future.

"It's about making identity easy. Right now, identity is hard. What if identity were easy, what are the things you could do?" Martin said. "It's this idea that services and your personal accounts and your information can just follow you and all you need is your identity."
Much like how Apple's iPhone 5S uses a fingerprint sensor to authenticate the user's identity, Bionym's bracelet—called the Nymi—uses sensors to capture a person's unique cardiac rhythm, or ECG, to wirelessly unlock or gain control of their devices.
So whenever a person is wearing their Nymi, they automatically have access to their devices without having to enter a password.
